Disk space is cheap?
- synaptic package manager not supported
I wouldn’t recommend using synaptic even if it was. The gnome packagekit based tool is better for simply installing apps. Apt from the command line is better in general.
- not using swap partition be default. I had to force it to use
Would have to fire up a vm to confirm, but I am going to doubt this is the case for most installs. More information needed.
- software center had nothing to show, I had to reinstall . now its showing softwares
It may have just been indexing/refreshing.
- dont have wide range of softwares.
I beg to differ. You can use any software available on Linux in general as well as windows software through wine.
- after installing chromium ( I use chormium on linux instead of chrome) chromium took 500 to 700mb memory
Disk space is cheap. If you mean “ram” yeah this isn’t unusual. Facebook uses 1gb of ram all to itself on most browsers.
- sometimes debian became laggy (for 2,3 minutes) this is maybe because I have a slwo HDD.
This is a criticism I have on Linux is weak I/o interactivity. You might try the mq-bfq scheduler. Google info about it as it’s probably complicated to switch it as default.
- unable to install openjdk and other packages from ppa repository( may be because buster is new and ppa has no support. I don't know)
You don’t want to be adding any repositories at all ever unless you trust the maintainer and they are specifically designed to work with Debian. Ubuntu packages are not compatible. The correct way is to find a package for Debian or rebuild the package to work with Debian.
So far I like this new Buster. old users or those who know linux more. if there is a mistake on my end. kindly notify. there is a need to learn more.
We would be happy to help.
